A double-barreled syringe is provided which includes a mixing tip which is detachable after the tip is locked to the syringe body, so that the tip may be replaced by a locking cap. Locking occurs when a neck extending from the body between two shoulders is inserted into a bore in the tip (or, alternatively, the cap) and the tip is rotated so that two symmetrically opposed tabs attached to the tip are each received within a recess determined by a shoulder and a locking rib attached to the shoulder, and two diametrically opposed detents extending from the neck are each received within a recess in the bore surface.

1. A syringe for dispensing two viscous materials as an admixture, comprising: an integrally molded housing having a first and a second barrel that are symmetrical and fixedly opposed along a center line, the barrels are bounded at a discharge end by first and second shoulders, respectively, each shoulder having a generally planar surface and is coplanar with the other planar surface, a generally cylindrical neck extending from and symmetrically disposed between the shoulders, the neck including first and second outlet passages in fluid communication, respectively, with the first and second barrels, and a generally flat gripping member disposed at a proximal end of the housing; a first mating assembly having opposed first and second locking ribs symmetrically disposed with respect to said neck and rigidly attached to said first and second shoulders, wherein said first mating assembly is configured to receive one of a mixing tip and a locking closure cap; wherein said mixing tip has an inlet and an outlet, a generally cylindrical bore determined by a circumferential surface adapted to closely receive said neck; wherein the mixing tip further includes a second mating assembly having opposed generally planar first and second locking tabs symmetrically disposed with respect to said bore, the two mating assemblies conjoining when the neck is inserted into the mixing tip bore in a relative orientation, and wherein the two mating assemblies interlock when the mixing tip rotates in a first direction and the locking tabs slide under the first and the second locking ribs until a stop is achieved, the two mating assemblies are detachable when the mixing tip is rotated in an opposite direction; and wherein the mixing tip further including a static mixing element having a plurality of intertwined sections disposed within the cylindrical bore for mixing the two viscous materials as the two viscous materials are dispensed from the first and the second barrels.
